discogs: "3 vinyl split" release not possible to add

Sorry for being brief here for now. I will elaborate the problem later. Not sure if it is a discogs tagger only problem. Will investigate.

Not-technically speaking the problem is: Sometimes albums (releases in discogs speak) were put out on several vinyls (catalog numbers MM129A, MM129B, MM129C in this case). They all share the same master release. For example these 2 vinyls were available to buy separately:

https://www.discogs.com/release/830530-Dave-Clarke-Remixes-Rarities-1992-2005

https://www.discogs.com/release/830537-Dave-Clarke-Remixes-Rarities-1992-2005

(There is a third one MM129C but I don’t want to tag it because I don’t have the mp3, if that matters…)

Importing the first one works fine but when trying to import the second one, beets always wants to overwrite the previously imported one:

Not sure if it’s because the album/release name is the same or it is because of the same master release (https://www.discogs.com/master/93537-Dave-Clarke-Remixes-Rarities-1992-2005)

Setup

My configuration (output of beet config) is:

And thanks for the issue link, I just had the idea that in my case taking the catalognumber into account with dup finding would have helped. Awesome you are working on a configurable solution already! 😃

FWIW, it’s because they have the same artist and title—that’s how beets’ “duplicate detection” works. #4199 may be relevant to you, or you may just choose “Keep all” at this prompt.
